Hantavirus Outbreak on Cruise Ship Highlights Rodent‑Borne Health Risk
Hantavirus—an extremely rare rodent‑borne virus with no vaccine or specific treatment—has a cruise‑ship cluster in the Atlantic: the WHO confirmed one case and suspects five more, with three deaths reported. The illness can start with fatigue and fever and may progress to hantavirus pulmonary syndrome, a severe respiratory disease. Transmission mainly occurs when people disturb rodent droppings, urine, or saliva, and prevention relies on avoiding aerosolized particles and using protective gear during cleanup; human‑to‑human transmission is possible but rare.
